SafeAssign is based on a unique text-matching algorithm capable of detecting exact and inexact matching between a submitted paper and source material. This proprietary algorithm analyzes submission text and optimizes the words and terms to be searched against multiple data sources. Results returned from each service are further processed based on both the weight returned by the search service and comparative weighting by the SafeAssign algorithm, which determines the result set to be returned in the Originality Report.
Student submissions to SafeAssign are compared against several sources:
- Institutional document archives: Contains all papers submitted to SafeAssign by users in their respective institutions.
- Global Reference Database: Contains over 59 million papers volunteered by students from Blackboard client institutions to help prevent cross-institutional plagiarism.
- ProQuest ABI/Inform Journal Database: More than 3,000 publication titles, 5 million documents, and over 200 topical categories from the 1970s to present time and covering topics from Advertising to Women's Studies.
- Internet: SafeAssign searches across the broader internet for matching text using an internal search service.
The SafeAssign Global Reference Database is a separate database where students voluntarily submit copies of their papers to help prevent plagiarism. It is separate from each institution's internal database, where all papers are stored by each corresponding institution. Students are free to select the option to check their papers without submitting them to the Global Reference Database. Students are not required to submit papers to this database. They submit their papers voluntarily and agree not to delete papers in the future. Blackboard does not claim ownership of submitted papers.
Connect to the Global Reference Database
The Global Reference Database allows institutions to search their own data repository as well as many other data repositories. Access to the database is enabled by default. To connect to the Global Reference Database, ensure that the Blackboard Application servers are allowed to access the following host and ports.
These ports are for outgoing HTTP traffic only.
IP Address: 220.127.116.11 and 18.104.22.168
Ports: 80, 443
Allow incoming traffic on all established connections for Learn by allowing a connection with a flag other than SYNC on any port from the following IP Addresses: 22.214.171.124 and 126.96.36.199. SafeAssign makes web service calls to your Blackboard system from this IP.
The internet search indexes used by SafeAssign are designed for reliability, performance, and efficiency against the large scale of search queries executed by SafeAssign. These search indexes can't be refreshed as frequently as those used by consumer internet search services. Generally, these indexes can be expected to be current within 1-3 days of a change. Due to the combination of these search index characteristics and the weighting applied by the SafeAssign algorithm, results returned in a SafeAssign Originality Report may not be identical to results returned by a consumer internet search service for any individual sentence or phrase.
Previously, Blackboard SafeAssign relied on the Yahoo! BOSS service to provide results from the broader internet. Due to the deprecation of the Yahoo! BOSS service on March 31, 2016, Blackboard has developed an internal search service to provide internet results for SafeAssign. No customer action is required to enable the SafeAssign internal search service, as the change was made in the SafeAssign Central Service and applies to all clients.
The internal search service is built using the latest search crawling and indexing technologies, and allows Blackboard to significantly reduce dependency and exposure to third-party tools. Because the search service is now administered internally, Blackboard has the ability to enhance and refine search results over time and improve the overall SafeAssign product quality and performance. Additionally, any potential concern of client data being shared with Blackboard partners is entirely mitigated using this new approach to providing search results from the internet.
Due to the ever-changing nature of the internet, there may be occasions when the SafeAssign internal search service does not yet include specific webpages or websites and as a consequence SafeAssign Originality Reports may not identify potentially matching text within student works. When these situations arise, Blackboard will investigate the source web content and, if possible, add the content to the SafeAssign internal search service for future submissions.
The development of the SafeAssign internal search service further demonstrates Blackboard's commitment to supporting the SafeAssign product functionality and Blackboard Learn customers' use of the SafeAssign service. As always, Blackboard will continue to monitor SafeAssign for improvement opportunities and encourages customer feedback regarding search results and overall SafeAssign performance.
As a reminder, results returned in a SafeAssign Originality Report may not be identical to results returned by a consumer internet search service (e.g. Google, Bing, etc.) for any individual sentence or phrase. The results from the SafeAssign service are only meant to be a tool for use at the discretion of the teacher or instructor. Due to the size and scope of both academic subject matter and the number of resources searched by SafeAssign, the results are not meant to guarantee or otherwise indicate that plagiarism has or has not occurred. The assessment of potential plagiarism should reside in the hands of the instructor, and SafeAssign results should always be considered in the context of other resources and good judgment.
After a paper submission is processed, SafeAssign generates a report detailing the percentage of text in the paper that matches existing sources. The report also shows the suspected sources that return a match for each section of the submitted paper. Instructors can delete matching sources from the report and process it again. This is useful if the paper is a continuation of a previously submitted work by the same student.
In the Ultra Course View, SafeAssign generates an Originality Report for each part of the submission, including free form text answers and attachments.
SafeAssign officially supports English only, but the service has no technical limitations that preclude using it with other languages. The results may vary and aren't guaranteed. Blackboard has a partnership with another plagiarism vendor, TurnItIn. TurnItIn integrates with Blackboard Learn and is available for international clients or anyone who needs support for languages other than English. To learn more, see www.turnItIn.com.
